irowAnn' M. BARBER, 0E s'romne ron, CONNECTICUT, ASSIGNOR To 0. B.COTTRELL & sonsooMPANY, OF NEW YORK, N. Y., A CORPORATION OF DELAWARE.

and State of Connecticut, have invented anew and useful Improvement inCutting and Folding Machines, of which the'following is Iaspecification.

The object of my invention is to provide certain improvements in cuttingand folding machines whereby a plurality of superimposed narrow webs maybe positivelyand accurately fed in absolute register through the sheetcutting mechanism to the folding mechanism, thus permitting themechanisms to be run at a much higher speed than would otherwise bepossible were the webs not so positively and. accurately fed.

My invention more specifically comprises twopairs of coacting endlessbelts driven positively by sprockets and each pair of coacting beltshaving an interlocking engagement, the beltsbeing so arranged that theywill engage the margins of the superimposed webs, portions of'the beltsbeing cut away for permitting the action of the knives of the cuttingmechanism and the blades, of the folding mechanism.

A pmcticalembodiment of my invention is represented in the accompanyingdrawings, in which-' Figure-1 represents the cutting and fold- .ingmachine in side elevation,

Fig.2is a front view of the machine, and

Fig. 3 is a vertical section'taken in the plane of the line AA- of Fig.2, looking in the direction of the arrows.

v I have shown three sets of. rolls 1, 2; 3, 4; andf5, 6,arrangedtosuperim-pose six narrow webs.

The cutting mechanism'in'cludes a pair of coacting rotary cutters 7, 8carried by shafts 9, 10, mounted in the side frames of the machine. Thefolding mechanism includes the male folding cylinder 11 and femalefolding cylinder 12 carried by their respective shafts 13, 14, mountedin the side frames of the machine. cylinder 11 is shown as provided withtwo sets of grip ers 15, 16, and two sets of folding blades 1%, 18. rThe female folding cylinder is shown as provided with two sets offolding jaws 19, 20, arranged to coact with the folding blades 17 and18, respectively.

The sheet delivery mechanism is herein Specification of Letters Patent.

Application filed June 12, 1915. Serial No. 33,845.

The male folding CUTTING AND FOLDING MACHINE.

Patented Sept. 24, 19 1s.

shown as'comprising the endless tape car-- guide '23, rotary dropper 24,and

riers 21,22, endless delivery carrier 25.

The cutting mechanism, folding mechanism,'and delivery mechanism may beof any well known and approved form.

The superimposed narrow websare positively fed through the cuttingmechanism to the folding mechanism by two pairs of coacting endlessbelts 26,27, and 28, 29.

The-upper ends of the belts 26, 28, pass around a drum 30 and the lowerends of said belts pass around the male foldingcylinder 11. These belts26, 28, are provided with holes 31, 32, arranged to be engaged bysprocket teethon the folding cylinder 11. The endless belts 27, 29, passaroiuid the drum 33 at their upper ends and at their lower ends-theypass around sprocket wheels,

34,35, mounted ona suitable. shaft '36. These belts 27, 29,;are alsoprovided with holes 37, 38, arranged to be enga ed b sprocket teeth onthe wheels 34, 35. The pair of belts 26, 27, have an interlockingdriving engagement by providing one ofthebelts with pins 39 arranged toenter corresponding holes 40 in the other belt. Similarly, the belts 28and 29.have an interlock- 1i)ngengagement by providing one of the e tscylin'derll that the pairs of belts will trav el" together from thedrums 30, 33, downwardly through the rotary cutters 7, '8 toflthefolding cylinder 11 and from thencea short distance 'a-longthe-periphery'of the folding cylinder before the belts 27, 29, arepermits ted tov separate from their corresponding belts 26, 28. Thispermits the grippers 15 and 16 to have ample time 7 on the advance edgeof the webs while the webs are being held in register on the peripheryof the folding cylinder 11 thus permitting the mechanism to be run at amuch higher speed than would otherwise be pos- S1 e.

Gearing 47, 48, 49,50, 51, 52, 53, 54,

56, 57, 5s, 59, e0, 61, 62,63, 64, e5, 66, prowith pins 41, arranged toenter cor respondlng holes'42 in the other belt.-

to close gently narrow webs through the cutting mechanism to the foldingmechanism where the advance edges of the webs, while held in register bythe belts, are engaged by either the set of grippers 15 or 16.

At about the time the grippers engage the webs, the cutting mechanismoperates to sever the same and the sheets are then car ried around theperiphery of the cylinder 11. until the folding mechanism wants to foldoff the sheets to the cylinder 12, from which cylinder the sheets aredelivered by the tape carriers 21, 22, guides 23, and sheet dropper 24:,to the delivery device 25.

It will thus be seen that the narrow webs are positively fed through thecutting mechanism to the folding mechanism in accurate register and heldin such register a sufiicient time on the male folding cylinder topermit the easy operation of the grippers.

A divisional application has been filed on the 16th day of October,1915,'Serial No. 56252, covering the cutting mechanism, and no claimtherefor is made herein. except in connection with the foldingmechanism.

It is evident that slight changes may be resorted to in the form,construction and arrangement of the several parts without departing fromthe spirit and scope of my invention; hence I do not wish to limitmyself strictly to the structure herein set forth, but

hat I claim is 7 1. In a machine of the character described, a cuttingmechanism, a folding mechanism, and means for positively feeding aplurality of superimposed webs through the cutting mechanism to thefolding mechanism, said means comprising coacting positively drivenendless belts having an interlocking engagement.

2. In a machine of the character described, a cutting mechanism, afolding mechanism, and means for positively feeding a plurality ofsuperimposed webs through the cutting mechanism to the fold ingmechanism, said means comprising 00 acting endless belts having aninterlocking engagement and sprockets for positively driving-the belts.

3. In a machine of the character" described, a pair of coacting rotarysheet cutters, a folding mechanism, and means for positively feeding aplurality of superim posed webs to and through the cutters to thefolding mechanism, said means compris- 7 gaging the margins of the webs,each pair of bolts having an interlocking engagement.

5. In a machine of the character described, a pair of rotary cuttersincluding enacting cutting blades, a rotary folding mechanism includingcoacting folding blades and jaws, and means for positively feedingplurality of superimposed webs through the cutting mechanism to thefolding mechanism, said means comprising two pairs of positively drivenendless belts engaging the margins of the webs, said belts havingcutaway portions for permitting the cutting blades to act upon the fullwidth. of the webs and the folding blades to act upon the full width ofthe sheets cut from the webs." 6. In a machine of the characterdescribed, a cutting mechanism, a folding mechanism including a cylinderand its grippers, and means for/positively feeding a plurality ofsuperimposed webs through the cutting mechanism to said grippers, saidmeans comprising coacting positively driven endless belts arranged tohold the sheetsin register on the said cylinder prior to the closing-ofthe grippers.

In testimony that I- as my invention, I have signed my name this tenthday of June,cl915.

HOWARD M. BARBER."
